We have trust backwards, claiming to trust God in the big things (i.e. of the soul) while demonstrating little if any trust God in the little things (i.e. of the body). In His homily on Matthew 14: 14-22, St. John Chrysostom makes the point that the disciples were only ready to believe that Christ was the master of the unseen world after they had learned that he was the master of the things they could see. If we have skipped that first step - as is evidenced when we exhibit no confidence in His ability to rightly govern and bless our bodies and our budgets - it is quite possible that we are fooling ourselves when we say we trust him to rightly govern and bless our souls.
